Evolution has created a human species whose members are capable of great evil.
To hear some evolutionists talk, humans are incapable of evil. Nature has instilled within us all sorts of virtues, from kin-selection to group protection to maternal and paternal instincts, to general altruism. As a result, we do not need to worry about the possibility of evil. Humans are not capable of such things.
As a matter of fact, no evolutionist would say this. Of course evil is possible. If evolutionary theory implied that evil were not possible, the world around us would provide immediate proof that the theory was incorrect. Evolutionary theory has to be consistent with observed facts, and the observed fact of the matter is that humans are capable of great evil.
Yet, the evolutionary response to theist concerns about morality in the absence of God only makes sense if we add this proposition that even evolutionists would deny as absolutely absurd that evolution makes evil impossible.
Some theists argue that, in the absence of God, we are at the mercy of unchecked evil. Morality requires a God.
The evolutionist responds by saying that this is not true - that evolution has provided us with moral sentiments and attitudes. These attitudes played an important role in our evolutionary past, giving those human ancestors who had those qualities an evolutionary advantage over those who did not. This is one of the explanation for the presence of these qualities in humans today. They will not disappear simply because there is no God.
This response misses the point by such a wide margin it could sensibly be taken as a joke to those who hear it.
Even if all of this were true, evolution has created humans that are capable of great evil. The evolutionist has to accept this as true. The evidence is found every time we pick up a history book or watch a general news broadcast. We are surrounded by evil. Holocausts, slavery, tyranny of all sorts and descriptions, the subjugation of women, apartheid, racial animosities, rape, spouse abuse, child abuse, fraud, theft, and murder are everyday occurances.
Evolution has created a human species whose members are doing great evil, right?
The only sensible response that the evolutionist can give to this statement is that it is true.
"So, what are you going to do to prevent it? Or, at least, to minimize it? How are you going to prevent the next holocaust? How are you going to prevent the next Hitler or Stalin? How are you going to keep my child safe from predators? How are you going to keep my daughter from being raped or keep her from being murdered by a jealous boyfriend? How are you going to keep the racist from lynching my son, and prevent them from denying him opportunities for a high quality of life in the real world without judging him by the color of his skin?"
The evolutionist then turns to his theory of evolution and gets . . . nothing.
There is absolutely nothing the evolutionist can say to address these concerns.
The evolutionist can talk until he is blue in the face about how evolution favors altruism and promotes parental affection.
Against this, the theist concerned about the relationship between morality and God merely has to ask, "Are you telling me that, because of evolution I do not have to worry about these possibilities because the theory of evolution says that humans are incapable of such acts? We can count on their general altruism and kin-selection to prevent these things from happening?"
"Well of course not."
"Then answer the fracking question!
What is your plan for preventing or at least reducing the evils that, contrary to all of your claims of evolved altruism and moral fitness, humans are obviously still willing and able to commit?
Don't tell me that evolution has already dealt with the problem. It hasn't. In fact, if we accept the assumption that we are evolved beings, evolution created the problem by making us a species capable of committing such evils.
